Wordle is a toy for generating â€œword cloudsâ€ from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.

Wordle for my blog
And from what’s shown here I believe it tracks some of the very recent posts and is not a deep-level analysis which usually Tag Clouds should be doing. But what’s interesting is the lovely designs in which the clouds are generated and you get options on the layout, orientation and colors.
